While I completely agree with blaXXer & Starforce (Who are far more experienced than myself, of course), if it's CGI level, just remake it. If it's just a high poly model, I have spotted some reducepoly and reducepoint utilities in LW7, which usually shears off a fair amount of useless crap. Doesn't max have something like this?
...Of course, it's not always very accurate, and has (at times) torn the front hull from some prototype designs I've made... Thank god they don't compress the interior until the entire frame is done. :lol:
